Tick Tock Volt Clock

Engineers and tinkerer types, we've always got a voltmeter handy (because you just never know when you'll need it!). But keeping track of time? That's not so much in our wheelhouse. We're supposed to put down what we're doing and eat something once a day? What? Three times?!? Who can keep track of all that? If only there was a voltmeter for measuring hours and minutes, too!

Turns out, there is! The Analog Voltmeter Clock spells out the current time in a language we can understand: dual analog meters. The minutes meter drives the hours meter (hours hand moves in whole-hour increments) and they each roll back to 0 at the appropriate times. Powered by a single AA battery with a ATtiny44 main CPU, the lock fuse is unset so that tinkerers can reprogram it, if you so desire. Two easy-to-use adjustment knobs make setup a snap, so even non-engineers will have no trouble calibrating and understanding the readout.
